Explosions are a common cause of the fire. The following techniques involve the construction of buildings specifically designed to prevent fires. Techniques have proven effective in reducing the risk of explosions and fires, and often in subtle ways to help save lives.

The first effective technique is isolation. Isolation stops the explosion from reaching other areas of the plant through pipes and ducts. It prevents the pressure from a primary explosion from starting a secondary explosion and prevents the possibility of jets of flame issuing from long pipes. One must leave the work of installing explosion isolation valves and other preventive equipment to the experts.

Depending upon the maximum explosion pressure, vessels may be constructed to contain the explosion. Most vessels that may be at risk of dust explosions are designed so that they will absorb the force of an explosion and not rupture.

The second technique is suppression. There are 3 ways to avoid creating an explosive dust cloud without modifying the dust itself:

• By adding inert gas to the atmosphere. This will reduce the amount of oxygen in the process area and thus reduce the chances of explosion;

• By ensuring the dust is outside of its explosive (flammable) limits;

• By adding inert dust, however, is not suitable for many industries as it contaminates the product.

The above techniques are some main fundamental ways of preventing loss from fires right at the first stage of building an environment to live in or to work in.
